Version 3 of the patch-set.

Changelog

v2->v3:
  * Address comments from Rafael Wysocki:
    1. Instead of passing a pointer to a bool value to intel_c1_demotion_toggle(),
       cast the bool value to "void *. This removes a need for pointer dereferencing
       in intel_c1_demotion_toggle().
    2. Use reverse Xmass tree ordering for local variable definitions.
    3. A spelling fix.
v1->v2:
  * Address comments from Rafael Wysocki:
    1. Rename the sysfs file from 'c1_demotion' to 'intel_c1_demotion'
    2. Add a commentary about reading the feature only for 1 CPU.
    3. Update Documentation/API (new patch 3/3).
